CASH-BOX" FOR PNEUMATIC C'ASH-CARRIERSYTEMS.

SPECIFICATION forming part of Letters Patent No. 769,233, dated September 6, 1904. Application filed August 10, 1903. Serial No. 168,878. (No model.)

TO'CLZZ whmn it may concern:

Be it known that I, CHARLEs A. PFLUenR, a

citizen of the United States of America, and a resident of Chicago, Cook county,Illinois, have invented a certain new and useful Improvement in Cash-Boxes for Pneumatic Cash-Carrier Systems, of which the following is a specification. 1

In pneumatic cash carrier systems of the character in which small cylindric cash-boxes are forced through pipes pneumatic action difliculty is often experienced in relieving a box of its contents, owing to the fact that with boxes of a certain construction the contentssuch as paper money, paper memoranda,&c.-

being often necessary in such case-to pry the lead-pencil or other like contents out withv a article.

Generally stated, the object of my invention is the provision of a cash-box of such character that it will when opened afford ready and convenient accessto its contents.

A special object is the provision of an improved construction and arrangementwhereby the cash-box when opened will automatically lengthen to an extent sufficient to make it comparatively easy and convenient to remove the contents.

.It is also an object to provide certain details and features of improvement tending to increase the general efliciency and effectiveness of a longitudinally-extensible cash-box of this particular character.

To the foregoing and other useful ends my invention consists in matters hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 shows a cash-box embodying the principles of my invention, the box being closed. is a similar view showing the box open. Fig. 3 is a top plan view also showing the box open. Fig. 4 is a section on line 4 4 in Fig. 3. Fig. 5 is a horizontal longitudinalsection of the box in a closed position. Fig. 6 is a view similar to Fig. 5, but showing the box or desired manner.

Fig. 2

'in an opened condition. Fig. 7 is a view similar to Fig. 6 and illustrates of the invention. I

As thus illustrated, my improved cash-box comprises two relatively adjustable parts A a modified form .and B, each part being cylindric in shape and provided at its outer end with a head 1, of

felt or other like material. The section A is preferably composed of a relatively long cylindric portion a and a relatively short cylindric portion a, the latter arranged within the former. 'The sectionB is composed of a relatively short outer portion Z) and a relatively long inner portion 6. It will be seen that the portion a fits between the portions 6 and 6, while in a similar'manner the end of the portion 6 fits between the portions a and a. In other words, these shell-like sections or portions of the cylinder fit together and are arranged concentrically, as shown in the drawings. The section A is slotted longitudinally, and the section B is provided with a similar slot. When the box is closed, as shown in Fig. 5, these slots are out of register; but when the box is open, as shown in Fig. 3, then these slots register one with the other and combine to provide the box with a longitudinally-extending opening C. It will be observed that the ends of this opening through the side of the box are wedge-shaped or angular in form.

The lengthening of the box from the length shown in Fig. 5 to the length shown in Fig. 3, so as to provide a box which is practically capable of lengthwise expansion for the purpose of easing up the pressure or tension on the contents, can be accomplished in any suitable For example, the part6 can be provided witha slotb", extending circumferentially and spirally for a suitable dis' tance around the box. The end of the part a can then be provided with a projection (0 adapted to slide in said slot. With this arrangement a relative rotation between the parts A and B'will cause the projection d to traverse the slot 5 thereby not only permitting. the two sections to rotate relatively to each other, but also to shift longitudinally or lengthwise relatively to each other. In other words, a

' tents.

relative rotation of the sections A and B, brought about by twisting one section one way and the other section the other way, not

only serves to bring the slots into register with each other, and thereby provide the opening (1, but also to materially lengthen the box. Thus with my improved construction it is possible to stuff or crowd different things tightly into the box and to then relieve the box of its contents without difiiculty, owing to the fact that the box in opening expands and allows its end walls to draw away from the con- It is comparatively easy then to insert the fingers and pull out the money, paper memoranda, and other things in the box.

With further respect to the opening C it will be seen that the angularity of the end portions of this opening is of advantage in this way: The ends of this slot-like opening by being formed obliquely are adapted to provide guideways for the corners of the long shell portions throughout the entire relative adjustment of the two sections of the box. In this way these corner portions at the outer ends of the long slots in the two shells or sections are protected and prevented from becoming sprung or bent out of shape. In other words, were it not for the oblique or practically spiral lines along which the end portions of the opening (1 are formed the corners at the ends of the longer shell portions might become bent or sprung, and being exposed these corner portions would then fail to slide freely into place between the relatively long and short shells or cylindric sheet-metal parts; but with the oblique formation of the ends of the opening C the corner portions at the ends of the two long shells or sections are never exposed, and consequently can never make any trouble by failing to slide into place between the concentric sheet-metal shells of cylindric parts.

What I claim as my invention is 1'. A cylindric cash-box composed of a plurality of sections adapted for both rotary and endwise adjustment for the purpose of opening and closing the box, there being a suitable stop device for positively limiting the endwise extensibility of the box.

2'. An endwiseexpansible cash-box for use in pneumatic cash-carrier systems, there-being a suitable stop device for positively limiting I the endwise extensibility of the box.

3. A cylindric cash-box composed of'agplurality of relatively adjustable sections and pro vided at each end with an enlarged head of suitable material, said sections being provided with longitudinally-extending slots adapted to be brought into register by a relative rotation of the sections, one of said sections being provided with a cam-groove, and the other section being provided with means for engaging said cam-groove, whereby the aforesaid relative rotation of the sections produces an endwise expansion of the box.

4. A cylindric cash-box provided at each end. with an enlarged head of suitable material and composed of a plurality of sections, said sections being capable of both relative rotation and endwise adjustment, andeach section being provided with a lateral aperture, said apertures being adapted to be brought into and out of register by the relative rotation of said sections and there being a suitable stop device fer positively limiting the endwise extensibility of the box.

5. A cylindric cash box composed of a plurality of adjustable sections adapted to provide the box with an endwise-expansible chamher, there being'a suitable stop device for positively limiting the endwise extensibility of the box.

6. A cylindric cash-box composed of a plurality of adjustable sections adapted to provide the box with an end \vise-expausible chamber, each section being provided with a longitudinally extending slot having an obliquely-formed outer end, one section being provided with an oblique cam-groove and the other section being provided with means for engaging said groove, each section being composed of concentric relatively long and relatively short sheet-metal cylinders, the relatively long cylinder of each section sliding between the cylinders of the other section, whereby a relative rotation of the two sections serves to both extend the chamber of the box endwise and bring said slots into register, and whereby the corners at the inner ends of the relatively long cylinders are provided with guideways throughout the entire adjustment of one section relatively to the other.

7. In a device of the character described, a pair of cylindric shell-like members connected for a free limited rotary and longitudinal relative adjustment, each shell having its outer end provided with a head of suitable material.
